Isaiah 37:36-38
36Then the angel of the LORD went forth, and smote in the camp of the Assyrians a hundred and fourscore and five thousand: and when they arose early in the morning, behold, they were all dead corpses.37¶ So Sennacherib king of Assyria departed, and went and returned, and dwelt at Nineveh. 38And it came to pass, as he was worshipping in the house of Nisroch his god, that Adrammelech and Sharezer his sons smote him with the sword; and they escaped into the land of Armenia: and Esar-haddon his son reigned in his stead.
